Phone that accepts 2 sim cards..Is there any?

First of all - Boost doesn't use GSM. Thus, no SIM card. The GSM providers in the U.S. use modern (uncloneable) SIMs.

Yes. Sprint (and Vz.) are CDMA.

CDMA networks could use SIMs but the US CDMA carriers have chosen not to use them.

Can't imagine that you could seeing as it is a pre-paid service. Most prepaid wireless services in the US are not available outside the US. T-Mobile at least allows Canadian roaming on prepaid now but that's about it.

i don't know. i am asking because someone trying to sell me a boost unlimited w385 and said i can call dominican republic at no charge at a plan of $120 a month. he told me that the plan is from brazil but the phone number i googled it and it's from port st. lucie in florida. area code 772. is that possible or it's all BS?

Comp128v1 sim cards used a flawed encryption to protect the KI, this can be cracked using brute force tools, readily available. Once you have the KI, this can be written to a blank sim card, like the SuperSim availble on Ebay. These hold upwards of 16 numbers, you can switch between numbers by going into the menu, no need to reboot the phone to switch.

Later gen sims, comp128v2, use a stronger encryption which at this time can not be cracked using brute force.

All sims have built in safety measures to prevent unlimited brute force attacks, many people do not know this, but sims can only be turned on/off 65536 times before it stops working.

The comp128v1 sims are readily available new, via ebay, so you could always purchase one and switch your number to it. Problem is that there is no visible way to identify which ones are v1 and which ones are v2, you would have to do some research.

Most of these cheap phones sold by deal extreme are dual sim/dual standby. I personally have the zoho V90, and it has performed well for my needs. I do the same thing as you, forward my AT&T via voicestick to my international sim or to my local sim in the country I am visiting.

Here is my situation:

When I travel overseas I always bring 2 phones. One is my US T-mobile phone and the other one is an unlock phone with the overseas sim card on it.

And here is the set up. All calls to my T-Mobile US number is forwarded to my VoiceStick number (www.voicestick.com if you are not familiar). Then I set up my voicestick to forward the call to my overseas number.

For this set-up I will only be paying voicestick’s cheaper rate.

My question now: Is there a phone nowadays that accepts 2 sim cards so that I will be carrying only one phone while overseas?
